RFT Test Price in Pakistan: PKR 1,260 at Marham Lab

RFT stands for renal function test. It is a blood test that shows how well your kidneys are clearing waste from your blood. One sample measures urea, creatinine, uric acid and electrolytes, and it calculates your eGFR, the single number that says how well your kidneys are filtering.

Kidneys fail quietly. The National Institute of Diabetes and Digestive and Kidney Diseases puts it plainly: early kidney disease usually has no symptoms, and testing is the only way to know how well your kidneys are working.

KFT, Kidney Function Test and RFT: The Same Test

If your slip says KFT, RFT, RFTs, kidney function test or renal function test, it is one test. KFT stands for kidney function test and RFT for renal function test. Renal simply means relating to the kidneys, so the two abbreviations describe the same panel and Pakistani labs use both, sometimes on the same report.

You may also see it written as urea creatinine, or as a kidney profile. If a doctor asked for any of these, this is the test.

What the Test Measures

Each marker looks at a different part of kidney function.

What Your eGFR Number Means

eGFR is the number your doctor looks at first. NIDDK sets out the bands as follows.

You cannot raise your eGFR, but you can work to stop it falling further. That is why finding it early matters so much.

What High and Low Values Mean

Reference ranges for urea, creatinine and uric acid differ between laboratories and between testing methods, and they shift with age, sex and muscle mass. Read the range printed on your own report rather than comparing against a number you found online.

One value outside the range confirms nothing. Your doctor reads the whole panel together with your blood pressure, sugar and history.

Who Should Get Tested and When

Because early kidney disease is silent, testing is based on risk rather than symptoms. NIDDK advises getting checked if you have any of the following.

• Diabetes, and in that case every year
• High blood pressure
• Heart disease
• A family history of kidney failure

Test sooner if you have swelling in the feet or ankles, pass much more or much less urine than usual, have foamy urine, feel persistently tired, or take medicines that put a load on the kidneys.

How to Prepare

• No fasting is needed for the RFT on its own
• Drink water normally, since being dehydrated can lift your urea reading
• Tell your doctor about every medicine and supplement you take
• If your doctor has bundled the RFT with a lipid profile or a fasting sugar, fast for those instead
• Avoid heavy exercise the day before, because it can raise creatinine briefly

What Happens During the Test

• A trained phlebotomist draws a small blood sample from a vein in your arm
• The draw takes under a minute
• You may feel a brief sting and see a small bruise afterwards
• You can eat and drink normally straight away
• Your Marham Lab report is ready the same day and reaches you online

Conditions It Can Help Detect

An RFT is a screening and monitoring test rather than a diagnosis on its own. It helps find chronic kidney disease early, and it is used to follow kidney health in people with diabetes or high blood pressure, to check the effect of medicines on the kidneys, and to look into stones, gout and electrolyte problems.

Your doctor may pair it with a urine albumin test. NIDDK explains that a healthy kidney does not let albumin pass into urine, and that on the urine albumin to creatinine ratio a result of 30 mg/g or less is normal while more than 30 mg/g may be a sign of kidney disease. Blood and urine together give a fuller picture than either alone.

آر ایف ٹی یعنی رینل فنکشن ٹیسٹ خون کا وہ ٹیسٹ ہے جس سے معلوم ہوتا ہے کہ آپ کے گردے خون کو کتنی اچھی طرح صاف کر رہے ہیں۔ اسے کے ایف ٹی یا گردوں کا ٹیسٹ بھی کہا جاتا ہے۔ دونوں ناموں سے ایک ہی ٹیسٹ مراد ہے۔

اس میں یوریا، کریٹینین، یورک ایسڈ اور نمکیات کی مقدار دیکھی جاتی ہے، اور ای جی ایف آر نکالا جاتا ہے جو گردوں کی کارکردگی کا سب سے اہم عدد ہے۔

گردوں کی بیماری شروع میں خاموش رہتی ہے۔ اکثر کوئی علامت ظاہر نہیں ہوتی، اسی لیے ٹیسٹ ہی واحد طریقہ ہے۔ اگر آپ کو ذیابیطس یا بلڈ پریشر ہے، یا خاندان میں گردے فیل ہونے کی تاریخ ہے، تو یہ ٹیسٹ باقاعدگی سے کروائیں۔

مرہم لیب میں آر ایف ٹی کی قیمت 1,260 روپے ہے، جو 1,800 روپے سے کم ہے۔ اس ٹیسٹ کے لیے فاقہ ضروری نہیں۔ لاہور میں نمونہ گھر سے لینے کی سہولت موجود ہے اور رپورٹ اسی دن مل جاتی ہے۔

رپورٹ خود پڑھ کر علاج شروع نہ کریں۔ ایک عدد کا حد سے باہر ہونا بیماری کا ثبوت نہیں ہوتا۔ اپنی رپورٹ ہمیشہ ڈاکٹر کو دکھائیں۔

Final Thoughts

Kidney damage gives no warning until a lot of function is already gone, and an RFT is the cheapest way to see it coming. If you live with diabetes or high blood pressure, this is a test to repeat on the schedule your doctor sets rather than only when something feels wrong. Take the report to a doctor, because eGFR read alongside your other results says far more than any single number on the page.
